Hand over an optimization or debugging puzzle with a grain of concurrency concerns and I'm a happy camper. Sometimes, I can't help but feel like Sherlock Holmes. Hundreds of small seemingly unimportant bits of information that others haven't considered or might have missed circulate in my mind and, all of a sudden, a pattern emerges that leads to an answer. Not that I could ever compete with the genius of Sherlock, but I do think that years of practice have worked in my favor and have optimized my pattern recognition skills to an extent that would have made him tip his hat in acknowledgment.
